Fig. 4From: Drug voyager: a computational platform for exploring unintended drug actionHeat map of similarity between drugs. The x-axis and y-axis indicate the same 82 drugs. Each cell depicts the similarity between two drugs based on a similarity score of their drug-specific pathways (Gene-Sim) and corresponding color key. Green dotted squares display the anatomical, therapeutic and chemical (ATC) top-level classesBack to article page
